Network & Bus Cables
Network and bus cables are the physical cabling assemblies that carry data between PLCs, switches, distributed I/O, HMIs, and field devices across industrial Ethernet, PROFIBUS, PROFINET, and wireless network infrastructure. PLC Direct stocks Siemens network and bus cable products spanning Industrial Ethernet FC twisted-pair installation cable, IWLAN antenna connection cables, fiber-optic network cables, and pre-assembled fieldbus and connecting cables, available as surplus sealed, refurbished, and used hardware.
Where Are Network & Bus Cables Used in Industrial Environments?
Network and bus cables form the physical layer of industrial communication networks, connecting every active network device to its neighbors, whether over copper twisted-pair, fiber-optic, or coaxial cable. They are replacement items for any facility running Siemens PROFINET, Industrial Ethernet, IWLAN, or Foundation Fieldbus infrastructure, where cable damage, connector failure, or network expansion requires a specific cable type to maintain network integrity.
Facilities and operations that depend on network and bus cables include:
-
Manufacturing plants installing or extending PROFINET networks between SIMATIC S7 controllers, SCALANCE switches, and ET 200 distributed I/O stations, where IE FC TP standard cable is used for permanent structured cabling runs terminated with FastConnect RJ45 or M12 connectors.
-
Facilities using SCALANCE W IWLAN access points for wireless coverage of automated guided vehicles, mobile panels, or conveyor-mounted field devices, where N-Connect or R-SMA antenna cables must be replaced when the flexible antenna cable section fails from repeated movement.
-
Process plants and chemical facilities running Industrial Ethernet over fiber optic cable to achieve electrical isolation between control room and field network segments, or to span distances exceeding the 100-meter limit of copper twisted-pair links.
-
Oil and gas, pharmaceutical, and water treatment facilities with Foundation Fieldbus H1 installations, where 6XV1830 bus cable is used to extend or repair the 2-core shielded fieldbus segment connecting HART-compatible field instruments to DCS controllers.
-
Machine builders and system integrators connecting Siemens SIMATIC Mobile Panels to PROFINET infrastructure via pre-assembled PROFINET connecting cables, where a specific cable length is required to reach the mobile panel connection box from the network outlet.
A damaged or incorrectly specified network cable can degrade communication across an entire PROFINET segment or disconnect a group of field devices, making verification of cable type, connector format, and segment length essential before ordering a replacement.
Which Brands of Network & Bus Cables Does PLC Direct Stock?
This collection consists of Siemens hardware across four product families.
-
Siemens IE FC TP Cable Series: Industrial Ethernet FastConnect twisted-pair installation cable conforming to PROFINET Type A, available by the meter or in bulk drums for permanent structured cabling in PROFINET networks.
-
Siemens IWLAN Cabling Series: Pre-assembled flexible N-Connect, R-SMA, and SMA antenna connection cables for SCALANCE W IWLAN access points and mobile radio antenna installations, including railway-rated variants for transportation applications.
-
Siemens Fiber Optic Cable Series: Pre-assembled glass fiber optic trailing cables with SC and BFOC connectors for Industrial Ethernet FO links, and polymer clad fiber (PCF) bulk cable for shorter flexible optical connections.
-
Siemens Pre-assembled IE and Fieldbus Cables: M12 D-coded pre-assembled Industrial Ethernet connecting cables, Foundation Fieldbus H1 bus cable per IEC 61158-2, M12 power connecting cables for ET 200 distributed I/O, and PROFINET Mobile Panel connection cables.
PLC Direct stocks Siemens network and bus cables as surplus sealed, refurbished, and used hardware, depending on available inventory.
What Should You Know Before Ordering Network & Bus Cables?
Hardware condition options: Surplus sealed cables are unused and in original manufacturer packaging. Refurbished cables have been inspected and restored to serviceable conditions. Used cables are tested functional assemblies, with the condition stated on each product listing.
Compatibility and part identification: The IE FC TP cable is sold by the meter and requires Siemens FastConnect RJ45 or M12 field-assembly connectors for termination. The cable part number identifies the cable type but not the connector, which must be ordered separately and matched to the device port format. For pre-assembled cables, including fiber optic, IWLAN, Mobile Panel, and M12 connecting cables, the full part number encodes the connector type, cable length, and application rating; ordering a different variant with the same base number but a different length suffix will produce an incompatible assembly.
Warranty: All network and bus cable hardware purchased from PLC Direct carries a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products. PLC Direct supplies network and bus cable hardware for replacement and maintenance purposes and does not provide system design, programming, or integration services.
